3-hour time limit

The three-hour time limit in arc018 is a crucial component of the contest's format and contributes significantly to its overall structure and dynamics. It serves several important purposes:

Firstly, the time limit imposes a sense of urgency and encourages participants to prioritize their problem-solving strategies. With only three hours to complete all ten problems, participants must carefully allocate their time and focus on solving the problems they are most confident in first. This forces them to think critically about their approach and make quick decisions, fostering their ability to work under pressure and adapt to changing circumstances.

Secondly, the time limit levels the playing field for participants of varying skill levels. While more experienced programmers may be able to solve the problems more quickly, the time limit prevents them from gaining an insurmountable advantage over less experienced participants. This allows participants of all levels to compete fairly and showcase their problem-solving abilities within the same timeframe.

Furthermore, the time limit adds an element of excitement and challenge to the contest. Participants must race against the clock to solve as many problems as possible, creating a sense of competition and camaraderie among them. The time limit also prevents participants from spending excessive time on any one problem, encouraging them to move on and attempt other problems, thus broadening their problem-solving experience.

In conclusion, the three-hour time limit in arc018 is an integral part of the contest's format. It fosters critical thinking, prioritization skills, and time management abilities, while also leveling the playing field for participants of varying skill levels. Moreover, it adds an element of excitement and challenge, making arc018 an engaging and rewarding experience for all participants.
